Removing stains/marks off a BxW jpeg picture

I've managed to remove all the stains/marks off a BxW jpeg picture (from a scan of my neighbour's old family photo), with the exception of two conspicuous bits on one of the children's nostrils - see screenshot click here. What's the best way to remove them please?

The other stains - on even surfaces/clothing/the background - were easy enough to remove/camouflage with the help of Paint.net (latest v3). To achieve this, I used a combination of copy/paste (clone?), colour-picker & brush tools. I've got PSP9 as well, but didn't find it as easy to use, but willing to learn how to use it to remove the 2 stains.

It's important for us to get it as good as possible as the pic is going to be printed+framed, & presented as a gift. It has to be a DIY job as we cannot afford a pro service. G

€dstowe, yes you're right on both accounts. It was scanned as a colour pic as I wanted to retain as much of the original's 'tint' as possible. What I could do I suppose is convert to B&W, remove as much of the stain as possible & give it back it's original tint - or at least the closest I can manage it.

Ho-Lin-Sok, that's very good. I've just learnt how to use the clone tool properly! I'm going to give it a go. G

I have not seen your picture in the original form.However- many 'stains' and 'discolouration' on old prints are caused by imperfect fixing when originally made all those years ago, and the gradual oxidization of the silver content of the emulsion.To get rid of these ,the best way is to work on the original print before scanning.A careful application of metal/silver polish such as Brasso or Goddard's , allow to dry and buff off with a soft cloth/cotton wool- works wonders.

jack, most were circular stains, made by droplets of tea/coffee/oil - at least that's what they looked like to me. But good tip about discolouration cleaning, I'll try that next time (if I can get my hands on those cleaners you mentioned).

eedcam, I think your method may be suitable for even textures. But not so much for the 'uneven' structure of a nose with shadows & facial lines in this case. Or, I may have been doing it wrong!

Anyway, the clone tool worked quite well in the end, & the pics have been uploaded for printing. G
